What are the metal castings do we have?

Casting occupies a large proportion in the mechanical products, such as tractors, casting weight about accounts for 50 ~ 70% of the weight, 40 ~ 70% of agricultural machinery, machine tools, such as internal combustion engine for 70 ~ 90%. All kinds of castings, with most varieties of machinery casting, the most complex shape, the dosage of the largest also, accounts for about 60% of the total output of castings. The second is the metallurgical ingot mould and the engineering use of the pipeline.

Casting also have close relationship with daily life. For example, often use the handle, door lock, radiator, fluctuation conduit, POTS and a gas stove, iron, etc., are all casting. Classification of casting casting has a variety of classification method: according to the different metal materials used in, divided into steel, cast iron, cast copper, cast aluminum parts, casting of magnesium, zinc casting, casting titanium parts, etc

And each type of castings can be according to their chemical composition and microstructure is further divided into different kinds. If parts can be divided into grey cast iron, nodular cast iron, vermicular cast iron, malleable cast iron, alloy cast iron parts, etc.; According to cast molding method, can be divided into ordinary the casting sand mold casting, metal mold casting, die casting, centrifugal casting, continuous casting parts, investment casting, ceramic type casting, electroslag casting pieces, double metal castings, etc. With ordinary sand mold casting application most, accounts for about 80% of the total casting production. And non-ferrous metals such as aluminum, magnesium, zinc castings, mostly die casting.
